Win a Powacycle Puma

We have a Powacycle Puma electric bike, worth £599, to give away. The Puma uses a lightweight aluminium folding frame which, combined with a lithium ion battery, means that it weighs just 18kg.

There are three modes of operation: motor power only, with a top speed of 12.4mph, assisted power using the motor and pedals, or pedal power. The battery lasts for 14-18 miles on the flat when combined with gentle pedalling, and it recharges fully in six to eight hours. Go to www.powacycle.co.uk for more information on the range of bikes.
